Laser scanning is a surveying technique that uses a laser scanner to capture accurate and detailed 3D measurements of surfaces and objects on the Earth’s surface. It is commonly used in architecture, engineering, construction, and geology to create 3D point clouds of surveyed areas, which can be used for design, analysis, and monitoring purposes. Laser scanning is a non-destructive, non-contact, and efficient way to capture large amounts of data from complex or hazardous locations.
